| 3/4 K-3/2 |= 5/6

解

\frac{3}{4} K - \frac{3}{2} = \frac{5}{6}

K = \frac{8}{9} or K = \frac{28}{9}

十進法表記

K = 0.88888 \dots, K = 3.11111 \dots

解答ステップ

\frac{3}{4} K - \frac{3}{2} = \frac{5}{6}

絶対規則を適用する:

∣ u ∣ = a, a > 0

の場合は

u = a

u = - a

\frac{3}{4} K - \frac{3}{2} = - \frac{5}{6} or \frac{3}{4} K - \frac{3}{2} = \frac{5}{6}

\frac{3}{4} K - \frac{3}{2} = - \frac{5}{6} or \frac{3}{4} K - \frac{3}{2} = \frac{5}{6}

K = \frac{8}{9} or K = \frac{28}{9}
